Eavesdrop an iPhone without touching it or without installing crap on it?

Wonder if there are any tools to 'collect' a nearby phone signal. Looking to study penetration testing on a mobile network but do not know how far advanced is the app market yet. IPhone is the preferred choice because of its popularity, but if there's anything else out there that works on Android, for example, I would be interested too.
Tks.

When the person is talking on it, sneak up besides him/her and press your ear against the other end of the iPhone.

They sell those cheap amplifiers for old people at the dollar store. You know, the ones that could pass for a 1998 MP3 Player. You should get one of those. But if it isn't illegal, it's definitely frowned upon.

The tool is called an IMSI catcher, and Chris Paget demonstarted a low cost version (about 1500$) at DefCon 2010: http://www.wired.com/...one-calls/

It will not only work on an iPhone, but on any GSM phone.

  • Why is my iPhone selecting random areas that i'm not even touching? It isn't doing it at the moment but sometimes I'll be typing and it will hit the space button by itself and won't stop until I lock and unlock my phone How do I fix this?
  • Why is my iPhone battery so crap? It bugs me so much I have literally just taken it off charge and its already 98% and I don't play on it all the time I don't even touch it sometimes and it gets so low it can't even last a full day
  • Why does iphone 5/5s look like crap? The iphone 4/4s glass back was way shinier and glossy and looked way better than the iphone 5/5s ugly matte finish dull boring metal back. like why can't they make one with shiny glass for the cool people. and one with the dull metal back for the boring people.
  • Why do so many people have Iphones? I think there ABSOLUTE crap? The screen is tiny, it has no character, only one boring menu, the screen is dull, it COST 80 DOLLARS A MONTH and the stretched out design is UGLY. I think that even Samsung phone is even better than those overrated phones.
